Top 7 Node.js Performance Tips
Surviving in today’s digital dog eat dog world is not easy; one requires to jump on to the next big thing before anyone else eye’s on it. Similarly developing a robust Node.js application doesn’t mean you can sit and watch the show, it means it’s time for some further action; i.e. focus on improvising the app’s performance. And that’s what the following post is all about.

1. Overview – Node.js Development
Over the course of years, Node.js technology has gained traction among developed as well as developing countries like the US, UK, Australia, and India. Often known as a universal web and software development framework, the tech is highly recommended to develop chat engines, realtime app monitor systems, interactive tools and web pages, eCommerce marketplaces, online gaming portals, social networking websites all kinds of lightweight, effective/efficient, data-intensive real-time applications across numerous tech devices like smartphones, tablets, laptops, desktops.
However, its journey hasn’t been as dramatic as PHP, condemned to death or something by any measure but somehow Node.js development has managed to make it into the mainstream industries like none other.
2. When to rope a Node.js Developer?
Before you think of hiring services from a reliable Node.js development company in India it is very crucial to figure out why a business requires assistance from such technology. Why should you develop your application in Node.js?
Unlike other budding technologies, this one ranks amongst the topmost in-demand frameworks. And the reasons are many such as:
- Developing real-time, high-traffic apps is feasible
- Creates a win-win situation as coding can be done for both the client-side and server-side.
- NPM successively boosts the productivity of Node.js developers as it features a wide range of tools and modules.
- In comparison to many other languages, here Code execution is done at a lightning speed.
- Acts as a perfect solution for microservices (multiple processes) mostly found among enterprise applications.
So, you got the basics! Now, it’s time to dive a bit deeper into the details in regards to what is Node.js development used for and when you need to seek assistance from a reliable professional?
#1 API – APIs have been pretty much-in-demand these days. Almost all web applications require some kind of backend to communicate well with either databases or external services.
#2 Streaming applications – The usage of streaming services seems to be increasing now and then, ranging from listening to music or watching videos and so on. Gone are the days when in order to watch the content, you need to download it first which might take all day long due to slow internet. Now, binging your most favorite TV series is possible with a few clicks and high-speed internet. Where Node.js comes into the picture, you may ask? Many of you might not be aware of the fact that this technology, in particular, comprises several built-in streams clusters modules enabling developers to transmit a huge amount of data in chunks, sequentially. In simple words, temporarily storing or caching data is no longer required.
#3 Real-time applications – Due to its ability to handle lots of I/O operations, building real-time applications becomes easy and a doable job. For example, several collaboration tools are created where co-workers are found working on the same document and several chat rooms where people can talk to each other in real-time. With Node.js you integrate video call and voice chat funtionalities with WebRTC and Socket.IO. Nothing is impossible these days – all thanks to the emergence of Node’s Events API and WebSockets.
So these are the major reasons for the rapid adoption of Node js development and of course, it acts as a promising career for so many new web and mobile app developers. But creating a Node.js application won’t be of much help, what’s more, required is investing in off-the-shelf monitoring techniques and solutions that eventually help to detect issues and factors contributing to decreased Node js performance and the slow response times.
3. Crucial tips to consider to improve Node.js App performance
1. Run things in parallel
Now to make the most of this situation(parallel features), what needs to be done is optimize Node.js through a call named async.js.
2. Node.js Load Balancer must be Used
Using multiple application servers can help you to get good performance on apps developed in Node.js.
Have you ever come across Nginx? It’s an open-source HTTP server featuring in-built load balancing. This is not it, it is easy to configure all because of its wide range of features. And you know what’s the best part here, you won’t just be able to select a particular process to receive or handle more requests but also be able to add timeouts, enforce sticky sessions, and a lot more.
3. The Key to enhance performance – data handling methods
Optimizing these data handling methods is a sure-shot way to enhance the performance of your existing Node.js application. How sure-shot, you may ask? Well, this tip not just simplifies system processes but boosts overall app efficiency.
We all know that due to CPU/IO-bound operation, Node.js programs can be slow so what should be done is start by looking at how the data is handled. In any normal scenario, an API request is sent and a response is returned – this is how data fetching is done. Optimizing this might seem a bit tricky, isn’t it? Try pagination, web developers often use this to get it done right. What they do is they separate responses into batches of content. As a result, it can be easily browsed via selective response requests.
Another approach to consider is filtering. Here the results are restricted by the criteria of the request itself.
4. Instead of Going Forward, Play Reverse Proxy Server
Being an experienced Node.js development company in India, we do get horrified at times when we see application servers directly getting exposed at the core of high-performing sites to incoming internet traffic. These scenarios are generally for WordPress-based sites.
Great scalability is at the core of any Node.js technology but that doesn’t mean its other elements cannot do anything, for example, the web server-side can handle a lot of internet traffic reasonably well. But when you are dealing with a high-traffic site, the first and foremost step which needs to be taken is placing a reverse proxy server which is meant to protect the actual Node.js server from direct exposure to Internet traffic enabling a great deal of flexibility, especially when using multiple application servers.
Simplifying privilege handling and port assignments, serving static images look more efficient, crashes can be managed more subtly, and mitigating DoS attacks are some of the best advantages of using this method of the reverse proxy server.
5. Client-Side Rendering is a must
The likelihood of creating single-page apps seems to be increasing day in day out – all thanks to MVC/MVVM frameworks.
With the availability of many frameworks like Angular, Meteor and many other JASON can be consumed. Doing this won’t just save the bandwidth but also improve speed. After all, there is no point rather than sending layout markup with each request. A plain JSON is perfect for rendering on the client-side.
6. Implement SSL/TLS AND HTTP/2
In order to safeguard your application and websites, SSL/TLS configuration is a must and with the help of reverse server proxy Node.js developers are able to implement this functionality. Many Node.js development companies are also using this to prevent their clients’ application from any kind of suspicious activity.
There is no denying the fact that more than a hundred sites tend to secure all users on the internet by using Secure Socket Layer/TLS. As one of the top-rated Node.js development companies, our team of experts can assist you in generating such SSL/TLS links to the client by using a reverse server proxy.
7. Asynchronous programming
So how to kill two birds with one arrow? Simple, start using asynchronous APIs in your code. This might be quite challenging for novices so make sure to hire professionals from an experienced Node.js development company.
For starters optimizing a Node.js application might sound like witchcraft but actually it isn’t. Although it can be a little bit trickier there is no debate about that, hiring one of the leading Node.js developers in India who are capable enough to come up with an application that should be handling thousands of requests and able to grow as your users demand is worth the investment.
